Abstract

Volumetric calculations of slope deposits, direct measurements of rockwall retreat and chronological control based on lichenometry provide a wide range of rockwall retreat rates in Svalbard that appears consistent with previous evaluations from other Arctic areas. A triple-rate rockwall retreat is suggested for the last 2 millennia : very slow biogenic flaking, moderate retreat due to frost shattering and rapid retreat associated with post-glacial stress relaxation. Bedrock conditions appear to be the main control on retreat rates
